Probably question better suited for the dev@ list. But I afaik the answer
is there is no way to tell the difference, but probably safe to look at the
created time, HHs tend to be older.

Certainly makes sense to not allow it. Any idea why the node would be holding
hints for tokens that don’t exist?

There are 3 other nodes that have a mild case. This is one node is worse by an
order of magnitude. deleteHintsForEndpoint fails with the same error on any of
the affected nodes.

Is this happening in one node or all. Did you try to delete the hints via
JMX in other nodes?

Check for other errors about timing out during hint reply.

Subject: HintedHandoff
Hi -I had a question on hinted-handoff. We have 2 DCs configured with overall
RF = 2 (DC1:1, DC2:1) and 4 nodes in each DC (total - 8 nodes across
JMX ended up just with lots more IOErrors. Did a rolling restart of the cluster
and removed the HH family in the mean time. That seemed to do the trick. Thanks!

There is a JMX command to do it for a particular node.
But if you just want to remove all of them, stop and delete the files.

Oops, forgot to mention that, did I… Cass 1.1.10.
What is the sanctioned way of removing hints? rm -f HintsColumnFamily*?
Truncate from CLI?
This is ls -l of my /system/HintsColumnFamily/ btw - the only one with zero
size are the -tmp- files. It seems odd…

What version of cassandra are you using?
I would stop each node and delete the hints. If it happens again I could either
indicate a failing disk or a bug.

Can we get some more information...
- What is countPendingHints showing ? Are they all for the same row ?
- What about listEndpointsPendingHints are their different end points listed
there ?
- Can you turn up the logging to DEBUG on one of the machines that has the
increasing number of hints ?
The last time this came up on the list Jonathan Ellis said (something
along the lines of) if your application can't tolerate stale data then
you should read with a consistency level of QUORUM.
It would be nice if there was some sort of middle ground for an
application that can tolerate slightly st

Yes, I think current HintedHandOff implementation in 0.6.x cannot support
large hints, it is a risk in a production system.

Yes, you should increase your timeout if you are hinting big mutations
(or big rows that were built from smaller mutations).
